devg_get_vcapfuncs()

Get a table of your driver's video capture functions

Synopsis:

int devg_get_vcapfuncs (disp_adapter_t *ctx,
                       disp_vcapfuncs_t *funcs,
                       int tabsize);

Arguments:

ctx: A pointer to the disp_adapter_t structure that describes the graphics adapter.
fns: A pointer to a disp_vcapfuncs_t structure that your driver must fill with pointers to its video capture functions.
tabsize: The size of the table, in bytes.

Description:

A driver that contains a video capture module must provide an entry point called devg_get_vcapfuncs(). The graphics framework calls it to get a table of your driver's video capture functions.

Use the DISP_ADD_FUNC() macro to add function pointers to the table. It checks the tabsize argument and adds a function pointer only if there's space for it in the table.

This entry point is optional. A driver may not support video capture.

Returns:

0: Success.
-1: An error occurred.
